As of now web and computerized media are getting more notoriety and the utilization of PCs increments quickly. The programmers and malware makes the information transmission trouble. So prerequisite of secure transmission of information additionally expanded. To ensure the information different advancements are created. In this paper, an information concealing plan is created by LSB substitution utilizing double polynomial mathematical statement. By applying Double Polynomial strategy to cover picture utilizing LSB substitution, the length of shrouded messages will be expanded. The contrast between the single polynomial, and double polynomial were portrayed. Experimental results demonstrate that the stego-picture is outwardly unclear from the first cover-picture. The acquired results additionally reveals huge change as for a past work.
